Plan exportador de Moncaleano Guerrero Hermanos Ltda.

Para lograr el proceso de internacionalización es primordial que se elabore un plan para sustentar su ejecución. Como parte inicial se debe partir de la definición del producto que se quiere exportar teniendo en cuenta su partida arancelaria tanto a nivel nacional como en el estándar internacional. Partiendo de este punto, se comienza por la inteligencia de mercados, en la cual se analizan países, los cuales deberán cumplir ciertos requisitos deseados por parte del empresarios y sus objetivos al momento de hacer un plan exportador; para definir los países a los cuales se quiere llegar es necesario que se tengan aspectos claves y decisorios como lo son la población objetivo, la competencia presente en el país, balanza comercial entre los 2 países, canales de distribución, zonas de acceso, requisitos tributarios , ambientales, sanitarios, etc. con los cuales se tomara la decisión si se opta o no por entrar a ese país. Luego de tener definidos 3 países (objetivo, alterno y contingente), se analizan todos los costos que incurren directa e indirectamente en el producto, para poder definir el precio de venta local y analizar si es competitivo en el mercado nacional. Para iniciar en el proceso internacional es vital que se analicen los precios de la competencia en cada uno de los destinos de exportación y ver que tan rentable puede ser ésta actividad para la empresa. Para poder definir el precio de venta internacional se deben estudiar las diferentes cotizaciones de las SIA’s (sociedad de intermediación aduanera) que son entidades necesarias para la exportación de productos a cualquier destino. Escogiendo la opción que más se acomode a las necesidades de la empresa se define el modo en el cual se quiere hacer llegar el producto a su destino final, claro esta, dependiendo de término de negociación elegido por las partes comerciales y definido mediante los INCOTERMS. Luego, se entra la fase de comercialización internacional, en la cual se definen todas las estrategias para cada una de las 4 P’s de la mezcla de mercadeo (Producto, precio, promoción y plaza) en las que se establecen las pautas de entrada para cada país referente a los aspectos anteriores.

Análise de Ensino de Educação Física no 1º ciclo, comparando Professores generalistas e especialistas

RESUMO: Este estudo teve como objectivo analisar se a área de formação do professor que lecciona Educação Física no 1.º Ciclo do Ensino Básico – professores licenciados em Educação Física e Desporto, designados por professores especialistas e professores licenciados em Educação Básica, denominados por professores generalistas – interfere com o número de alunos em empenhamento motor. Assim, foram filmadas oito aulas, duas por cada professor, em duas Escolas do 1.º Ciclo do Ensino Básico, pertencentes ao Agrupamento de Escolas de Sacavém e Prior Velho, situadas na freguesia de Sacavém. A amostra foi constituída por quatro professores (dois licenciados em Educação Básica e dois licenciados em Educação Física e Desporto) e por 36 alunos pertencentes a duas turmas do 4.º ano. Como sistema de observação foi utilizado o Planned Activity Check, de Siedentop. A realização do estudo em questão permitiu concluir que a média de alunos em empenhamento motor por minuto foi maior nas aulas de Actividade Física e Desportiva, leccionadas pelos professores especialistas.ABSTRACT: This study has the main objective of analyzing if the educational area of a professor that teaches Physical Education in the first cycle of Basic Education – professors with a graduation in Physical Education and Sports, designated as specialized professors, and graduated professors in Basic Education, designated as general professors – interferes with the number of students in motor engagement. Therefore, eight classes were recorded, two by each professor, in two schools of the first cycle of Basic Education that belong to the Group of Schools from Sacavém and Prior Velho, located in Sacavém. The sample had four professors (two with a graduation in Basic Education and two with a graduation in Physical Education and Sports) and 36 students from two classes of the 4th year of school. The observation system used was Siedentop’s Planned Activity Check. This study led to the conclusion that the average of students in motor engagement per minute was higher in the classes of physical activity and sports taught by specialized professors.

Influence of vegetation on the nocturnal foraging behaviors and vertebrate prey capture by endangered Burrowing Owls

Restrictions in technology have limited past habitat selection studies for many species to the home-range level, as a finer-scale understanding was often not possible. Consequently, these studies may not identify the true mechanism driving habitat selection patterns, which may influence how such results are applied in conservation. We used GPS dataloggers with digital video recorders to identify foraging modes and locations in which endangered Burrowing Owls (Athene cunicularia) captured prey. We measured the coarse and fine-scale characteristics of vegetation at locations in which owls searched for, versus where they caught, vertebrate prey. Most prey items were caught using hover-hunting. Burrowing Owls searched for, and caught, vertebrate prey in all cover types, but were more likely to kill prey in areas with sparse and less dense vegetative cover. Management strategies designed to increase Burrowing Owl foraging success in the Canadian prairies should try to ensure a mosaic of vegetation heights across cover types.

The influence of project complexity on estimating accuracy

With the rapid development in technology over recent years, construction, in common with many areas of industry, has become increasingly complex. It would, therefore, seem to be important to develop and extend the understanding of complexity so that industry in general and in this case the construction industry can work with greater accuracy and efficiency to provide clients with a better service. This paper aims to generate a definition of complexity and a method for its measurement in order to assess its influence upon the accuracy of the quantity surveying profession in UK new build office construction. Quantitative data came from an analysis of twenty projects of varying size and value and qualitative data came from interviews with professional quantity surveyors. The findings highlight the difficulty in defining and measuring project complexity. The correlation between accuracy and complexity was not straightforward, being subjected to many extraneous variables, particularly the impact of project size. Further research is required to develop a better measure of complexity. This is in order to improve the response of quantity surveyors, so that an appropriate level of effort can be applied to individual projects, permitting greater accuracy and enabling better resource planning within the profession.

Mersenne numbers

These notes have been issued on a small scale in 1983 and 1987 and on request at other times. This issue follows two items of news. First, WaIter Colquitt and Luther Welsh found the 'missed' Mersenne prime M110503 and advanced the frontier of complete Mp-testing to 139,267. In so doing, they terminated Slowinski's significant string of four consecutive Mersenne primes. Secondly, a team of five established a non-Mersenne number as the largest known prime. This result terminated the 1952-89 reign of Mersenne primes. All the original Mersenne numbers with p < 258 were factorised some time ago. The Sandia Laboratories team of Davis, Holdridge & Simmons with some little assistance from a CRAY machine cracked M211 in 1983 and M251 in 1984. They contributed their results to the 'Cunningham Project', care of Sam Wagstaff. That project is now moving apace thanks to developments in technology, factorisation and primality testing. New levels of computer power and new computer architectures motivated by the open-ended promise of parallelism are now available. Once again, the suppliers may be offering free buildings with the computer. However, the Sandia '84 CRAY-l implementation of the quadratic-sieve method is now outpowered by the number-field sieve technique. This is deployed on either purpose-built hardware or large syndicates, even distributed world-wide, of collaborating standard processors. New factorisation techniques of both special and general applicability have been defined and deployed. The elliptic-curve method finds large factors with helpful properties while the number-field sieve approach is breaking down composites with over one hundred digits. The material is updated on an occasional basis to follow the latest developments in primality-testing large Mp and factorising smaller Mp; all dates derive from the published literature or referenced private communications. Minor corrections, additions and changes merely advance the issue number after the decimal point. The reader is invited to report any errors and omissions that have escaped the proof-reading, to answer the unresolved questions noted and to suggest additional material associated with this subject.

Understanding UK construction professional services exports: definitions and characteristics

Services are very important to the UK balance of trade; a surplus has been recorded for trade in services every year since 1966. Construction professional services exports (CPS), which cover architecture, engineering and surveying (AES), have also increased, contributing over £3bn to the UK trade balance in 2007. The changing environment of construction professional services exports complicates the validity of the characteristics and definitions of services as described in the research literature and official export statistics. Through semi-structured interviews undertaken with large consulting engineers and a round-table discussion with industry and government representatives, the research found that the impact of globalisation and the changes in the construction business environment, such as increasing foreign ownership and changing forms of procurement, are not fully reflected in the official statistics. There have also been rapid changes in technology, procurement and methods of delivery which have impacted exporting AES firms and a more appropriate set of characteristics is needed to better reflect the project-specific and knowledge-intensive nature of AES firms.

The next generation of scenarios for climate change research and assessment

Advances in the science and observation of climate change are providing a clearer understanding of the inherent variability of Earth’s climate system and its likely response to human and natural influences. The implications of climate change for the environment and society will depend not only on the response of the Earth system to changes in radiative forcings, but also on how humankind responds through changes in technology, economies, lifestyle and policy. Extensive uncertainties exist in future forcings of and responses to climate change, necessitating the use of scenarios of the future to explore the potential consequences of different response options. To date, such scenarios have not adequately examined crucial possibilities, such as climate change mitigation and adaptation, and have relied on research processes that slowed the exchange of information among physical, biological and social scientists. Here we describe a new process for creating plausible scenarios to investigate some of the most challenging and important questions about climate change confronting the global community

Terahertz analysis of stratified wall plaster at buildings of cultural importance across Europe

Terahertz (THz) radiation is being developed as a tool for the analysis of cultural heritage, and due to recent advances in technology is now available commercially in systems which can be deployed for field analysis. The radiation is capable of penetrating up to one centimetre of wall plaster and is delivered in ultrafast pulses which are reflected from layers within this region. The technique is non-contact, non-invasive and non-destructive. While sub-surface radar is able to penetrate over a metre of wall plaster, producing details of internal structures, infrared and ultraviolet techniques produce information about the surface layers of wall plaster. THz radiation is able to provide information about the interim region of up to approximately one centimetre into the wall surface. Data from Chartres Cathedral, France, Riga Dome Cathedral, Latvia, and Chartreuse du Val de Bénédiction, France is presented each with different research questions. The presence of sub-surface paint layers was expected from documentary evidence, dating to the 13th Century, at Chartres Cathedral. In contrast, at the Riga Dome Cathedral surface painting had been obscured as recently as 1941 during the Russian occupation of Latvia using white lead-based paint. In the 13th Century, wall paintings at the Chapel of the Frescos, Chartreuse du Val de Benediction in Villeneuve les Avignon were constructed using sinopia under-painting on plaster covering uneven stonework.. This paper compares and contrasts the ability of THz radiation to provide information about sub-surface features in churches and Cathedrals across Europe by analysing depth based profiles gained from the reflected signal. © (2013) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
